TAMPA — Trayvon Martin's parents are expected to be at a rally this evening organized by a Tampa City Council member.

Martin, 17, was unarmed when he was shot last month in Sanford by neighborhood watch volunteer George Zimmerman, who told police the teenager looked suspicious and the shooting was in self-defense.

City Councilman Frank Reddick, who is a friend of the Martin family attorney, said he organized the rally as a call for justice. It is scheduled to begin at 6 p.m. at the 34th Street Church of God, 3000 N 34th St.

"A lot of people have been traumatized by this," he said. "People are frustrated, and they want to come out and let the family know that we stand by them."
